ADMINISTRATOR, OF GREENWIC CONNECTICUT.

SPURIOUS COIN DETECTOR.

Application filed July 6,

To all whom it may concern.-

Be it known that Lnororn Bnaem, deceased, late a citizen of Russia, and resident of Brooklyn, in the county of Kings and State of New York, has invented new and useful Improvements in Spurious Coin Detectors, of which the following is the specification.

This invention relates to devices for testing coins, and has for its object the provision of a novel balance device formed with holding slots designed to receive coins of different denominations, one at a time, discrepancies in the sizes of the coins being indicated by refusal of the coin to enter the slot or by its slipping through the slot, and discrepancy in the weight being indicated by too little or too great movement of the balance arm.

An important object is the provision of a device of this character which will be very simple and inexpensive in manufacture, neat in appearance, compact, efiicient and durable in sevice and a general improvement in the art.

With the above and other objects and ad vantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illus trated in the accompanying drawings, in which: 1

Figure 1 is a side elevation of the device, Figure 2 is a plan View, Figure 3 is a cross section taken through the pivotal connection, and Figure 4. is a plan view of the base.

Referring more particularly to the drawings, the numeral 10 designates a base constructed of any suitable material and carr ing spaced uprights 11 which may be secured thereto or formed integrally thereon, as preferred. The upper ends of the uprights are formed with bearing holes 12.

In connection with the above described base, I prov'de a balance arm 13 which is formed at opposite sides with pins or trunnions let engaged within the holes 12 so that the arm is pivoted. The shorter end of the arm has its underside weighted as indicated at 14 and has its longer arm formed with slots 15 defined by overhanging projections 16. The dilferent slots are of different sizes and are intended to receive coins of different denominations.

The slots for the heavier coins are naturally nearer the pivot point than the 1923. Serial No. 649,942.

slots for the lighter coins. It is preferable that the balance arm be inscribed adjacent each coin slot with a legend indicating the denominations of the coin intended to be inserted in that particular slot. From an inspection of Figure 3 it will be seen that the slots will receive gold coins of $20.00, $10.00, $5.00, $8.00 and $2.50 denominations and. silver coins of $1.00, and 25.

I11 the use of the device any coin to be tested is inserted into the proper slot as indicated by the legends. If a coin is too thick to be genuine or of too large diameter, it will not enter the slot at all, while if it is too thin or of too small diameter to be genuine it will pass entirely through, thus indicating its spurious nature. If the coin is of the proper size but of the wrong weight, the arm will either fail to swing upon its pivot 14, or else will swing too far, again indicating that the coins are counterfeit or else that they have been sweated or plugged, as is a common occurrence in the matter of gold coinage, or else that the coin is of an unauthorized alloy. It is of course necessary that the positions of the various slots be carefully gaged, so that a $2.50 gold piece, for example, will swing the balance arm just as freely as will a $20.00 gold piece.

From the foregoing description and a study of the drawings, it will be apparent that I have thus provided a simply constructed and consequently inexpensive device which will positively operate to test coins and detect all counterfeits. The device is well adapted for use in any business and is neat in appearance and rapid in action. Owing to the simplicity of the construction and the fewness of the parts it is apparent that there is nothing to get out of order so that the device should have a long life and satisfactorily perform all of its functions.

lVhile I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the sub 'oined claim.

Having thus described my invention I claim:

A device of the character described comprising an elongated supporting base formed at one end with spaced upstanding ears, an elongated lever disposed between said ears and formed at opposite edges of its intermediate portion nearer one end than the other, with angular extensions constituting trunnions pivotally engaged through said ears the shorter arm of said lever being Weighted and normally resting upon the top of said base at one end thereof, and the longer arm of the lever being formed with a plurality of slots of different Widths and lengths adapted to receive coins of different denominations tobe tested, said longer arm of the lever being inscribed with legends opposite the respective slots for indicating the denomination of coins to be engaged therein; r

In testimony whereof I, WOLF BRAGIN, administrator of the estate of Leopold Bragin, deceased, affix my signature. I l VOLF BRAGIN, Administrator of Leopold Bragin, deceased.
